As seen in https://github.com/Perl/perl5/issues/21366 Karl Williamson
came up with a better fix to #1060679 which doesn't have the side effect
(crash) seen here: revert unbreak-locale-initialization.diff and add
-DUSE_NL_LOCALE_NAME to ccflags.

My initial tests seem to confirm this. I'll try to push the fix in
sid hopefully this weekend, unless the 5.40 transition is imminent. If
nothing else the testing exposure might help people trying to convince
Ubuntu to fix this in their stable release.
